just want to get some feedback on the subject matter of evacuation for PWD.
I know Part B, covers very little on the subject and BS5588 is superseded with BS9999 and the NDA document, while interesting and a good starting point, is very prescriptive.
How do you deal with subject matter?
Do you consider it at design stage
or leave to the fire application (or the person doing the fire certificate application)
or do you expect the client to deal with it through management?
Have you considered any alternatives to the ‘Refuge’ concept?
Any personal experiences.

There is a seminar in WIT regarding BS 9999 is to replace BS 5588 as of 6th April 2009 and will be the primary British Standard on Fire Safety Design from that date.
This seminar is being offered in association with The Department of Architecture within the School of Engineering at Waterford Institute of Technology on Friday 3rd April.

You really have to keep it in consideration when designing from the start.
I can remember from experience a disastrous redesign was needed on a nursing home I worked on – basically the entire concept was rendered void because the circulation and means of escape didn’t comply.
You don’t need to be an expert in fire regulation but if you maintain a familiarity with the requirements for the building type from the start you won’t go too far wrong and any extra requirements at fire cert application stage will be easier to accommodate.

I work in the Disability sector, though I’m not an architect. Here’s a few thoughts;
1) I didn’t think the NDA document was prescriptive at all. It provides lots of information about different technologies, but every building is different, so it really can’t be perscriptive. It seems to be aimed at Health & Safety people, rather than architects or engineers, though there isn’t much else out there for technical heads.
2) First step would be to talk to the PWD who will end up using the building. Understand how they will be using the building, and what barriers they encounter in their current building. They will probably tell you things like;
– We hate using Evac chairs, especially if we have to be lifted in/out of the chair by workmates
– We hate being left at the refuge zone while everyone else gets out. Seriously, would you accept this?
– We hate buildings that have inaccessibility features ‘designed in’ for no good reason other than style, such as level changes where no level change was necessary,
3) The best alternative to refuge zones is to design the building so that the vast majority of PWD can get out promptly and independently. So for multi-story buildings, make sure that the lifts are specced to be safe for use during evacuations (see BS 9999 for spec).
4) Other suggestions – Make sure that visual fire alarms are wired in from the start. Make sure that the interior design uses colour contrast effectively to highlight key routes, and features such as handrails. Ensure handrails are of appropriate shape (circular profile), fitted on both sides of any stairs and ramps, contrast in colour against the background, turned into the wall at start and end, and not made from metals that make them difficult to use in cold conditions. Make sure that there is little or no glare. Make sure that all fire exits have level egress, with no steps, stairs and no exits onto grass or gravel. Consider use of LED signage at emergency exits, for great conspicuity (sp?).
5) If a refuge zone is used, make sure there is a two-way communicaitons device fitted, and make sure that persons waiting at the refuge don’t impinge on others who are moving to evacuate.
